Security Quantitative Risk Analysis of Ethylene Horizontal Tanks of a Petrochemical Company

Leakage frequency of ethylene horizontal tanks and its attachments and may lead to risk accident were analyzed by SAFETI and LEAK quantitative risk analysis software of Norwegian DNV company. Through the simulation results of four accident scene, which gas leakage of the tank, tank rupture, leakage in the pipe from the tank to the pump, leakage in the pump and its export pipe, evaluated the effect of leakage, radiation, explosion to the staff and installations in the factory so that determined the risk of casualties and property loss in ethylene tank farm.
